About 20 kilometers (12 miles) south of Trapani, and just north of Marsala, acres of salt flats stretch in shallow lagoons, punctuated by crumbling windmills. This region has been producing bright white salt with intense flavor since Phoenician times, and a Museum of Salt lays out the process in a restored windmill, with everything from diagrams of the Archimedes screws used to pump water between flats to the wide, straight shovels used for skimming the salt into towering white mounds. Bags of the stuff can be bought at the gift shop, so you can take home a taste of Sicily.
